Suggestions on DIY LED Amplifier? (make LED's go to the beat)

First:
System: http/bit.ly/1cjC6JH
LED Lights: (3x) http/ebay.to/1AuoGGt

Secondly currently I have them hooked up direct with a switch to a 9V battery and they light up perfectly. Instead of me going out to buy a amplifier is there any way I can bypass it. I know I can do this with a TIP31 Transistor but I don't have one of these and it would seem near impossible to do without a soldering gun and without all three wires touching. Shouldn't their be a way to send current to the lights with the battery with the speaker wires also hooked up.

It will work if I disconnect the battery and hook with speaker wires up to the + and - but I have to have the music on blast and bass up all the way. I just need that extra kick, ya know.


EDIT:
I got something going. I don't know what, but I got something.

Is it safe to keep it like this? I'm not worried about blowing out the LED lights but will it harm my system?

buy the cheapest audio amplifier you can find have the lights on the speaker of the audio amp.

I got something going. I don't know what, probably not the safest but I got something. Going to upload a video with a diagram.

if you have a voltometer measure the voltage of just the speaker wires and then between the negative and the led lights. if they are too far off you might be damaging your system.
